 Question 22238: 5e+4f=9 4e+5f=9 how do u solve this in linear equation form,in substitution, and graphingAnswer by MORUPHOSUOLALE(24)   (Show Source): You can put this solution on YOUR website! SOLUTIION ___________ 5e+4f=9 -eq--1 4e+5f=9 -eq--2 This is a simulateneous equation. By subtituion method from -eq 1 f= (9-5e)/4 plug in (9-5e)/4 for f in eq-2 4e+5(9-5e)/4 = 9 4e + [{45-25e}/4]=9 16e+45-25e=36 BY multiplying through by 4 and open the bracket. -9e=36-45 -9e=-9 e=9/9 =1 substitue e=1 for e in any of the euation to get the value of f 4e+5f=9-eg---2 above 4(1}+5f=9 4+5f=9 5f=9-4 5f=5 f=5/5 f=1 SECONDLY THE GRAPH OF e-1=0 means e=1 so graph of F(e)= e-1 is a straight line graph similarly the graph of f-1=0 means f=1 is also a straight line graph My computer is not comapatible with drawing graph presently if not that i will be more than glad to show you how to draw the graph. But according to your problem, we can generalize that e=f=1 Which means the value of e and f is the same. They are both a straight line graphs. MORUPH .A.OSUOLALE CENTRAL PIEDMONT COLLEGE CHARLOTTE,NC
